All Sinomarin hypertonic products are derived from seawater. Sinomarin Isotonic products consist of 28% seawater and 72% purified water, maintaining a 0.9% salt (NaCl) concentration. In contrast, Sinomarin Hypertonic products are formulated with 70% seawater and 30% purified water, resulting in a 2.3% salt (NaCl) concentration. Both product lines contain identical mineral salts and trace elements, albeit in differing concentrations. Moreover, certain hypertonic products incorporate additional all-natural ingredients, such as sea algae extracts, for enhanced efficacy. Sinomarin products are 100% natural, free from drug substances, chemical additives, and preservatives.
Determining when to use isotonic or hypertonic products depends on specific nasal health needs. Sinomarin products, all being 100% natural, offer distinct advantages based on their salt concentration and function.
Isotonic solutions, with a 0.9% salt (NaCl) concentration identical to that of the human body, serve to effectively cleanse the nasal cavities. While they support nasal hygiene by washing away impurities like excess mucus, pathogens, allergens, and pollutants, they do not act as decongestants due to their salt concentration being the same as that of the nasal tissues.
On the other hand, Sinomarin’s hypertonic products contain a higher salt concentration (2.3% NaCl) than that of the human body. This higher salt level induces osmotic action, effectively drawing out excess water from swollen nasal tissues. As a result, these hypertonic solutions aid in relieving nasal congestion naturally, making them ideal for tackling symptoms of conditions such as common cold, allergic rhinitis, or exposure to pollutants.
Both isotonic and hypertonic solutions play vital roles in maintaining good nasal health. Isotonic solutions are perfect for routine nasal cleansing and hygiene. Meanwhile, hypertonic solutions not only cleanse but also act as natural decongestants by reducing swelling and congestion in the nasal passages.
Ultimately, the choice between isotonic and hypertonic solutions depends on the specific nasal health needs. They can be used alone or alongside medicated treatments, offering versatile support for nasal health.
Natural seawater typically contains a sea salt (NaCl) concentration ranging between 3.1% and 3.8%. While highly efficient in relieving congestion and restoring normal nasal breathing and function, pure seawater can be irritating to the nose, making its use unpleasant. A 2.3% salt solution represents the optimal concentration, ensuring the products are not only highly effective but also comfortable to use, all the while retaining significant levels of mineral salts and trace elements. Introduced as the first ever hypertonic sea water product for nasal care 25 years ago, Sinomarin’s hypertonic nasal salt solution was the holder of a patent for 20 years.
Sinomarin hypertonic stands as the only 100% natural, safe and effective solution for alleviating your baby’s nasal congestion and thinning viscous mucus for easy elimination. Its use may reduce reliance on medicated decongestants and potentially prevent the onset of secondary infections, like otitis. Additionally, regular use can aid in clearing your baby’s nasal passages, promoting overall nasal health (please refer to individual product details for age specifications).
Sinomarin products are 100% natural, free of drugs, preservatives and chemical additives, and can safely be used in these cases as supported by clinical data*.
*except for Sinomarin Cold & Flu Relief products due to the presence of eucalyptus & thyme.
All Sinomarin products can be used together with medicated treatments (e.g. local, corticosteroids, antihistamines, vasoconstrictors) to help improve the overall treatment efficacy. It is advisable to consult your healthcare professional.
There’s a prevalent misconception that hypertonic solutions cause nasal dryness because of their salt content. However, the osmotic mechanism, drawing water out of swollen nasal tissues, actually serves to hydrate the nasal tissue surfaces, aiding in alleviating nasal dryness.
All Sinomarin products are 100% natural, free of drugs preservatives and chemical additives ensuring their safety and suitability for all, including babies, pregnant or breastfeeding women, and individuals for whom medicated decongestants are not recommended**.
**Sinomarin Cold & Flu Relief and Sinomarin Plus Algae Cold & Flu Relief are not indicated for use during pregnancy & breastfeeding. Please read the instructions provided for each separate product for age limits and possible contraindications.
The seawater used in all Sinomarin products originates from the Bay of Mont Saint Michele, located at the French coast of Brittany. This region is famous for its remarkable tidal range exceeding 15 meters and powerful currents. The sea water is continuously renewed and enriched and free of contaminants, ensuring exceptional quality. The area undergoes rigorous monitoring by local official control authorities to maintain and guarantee its quality standards.
It is not recommended to use the same bottle for more than one person due to risk of cross-infection. It is neither sensible to use the same bottle with a different nozzle for the same reason.
Sinomarin can be used for as long as needed. Please check each individual product information leaflet.
With 25 years of marketing expertise and millions of units sold, there have been no reported serious incidents to regulatory authorities. The safety of the products is further reinforced by clinical trials. In the unlikely event of a known hypersensitivity to sea water, the use of Sinomarin should be avoided.
